I found that the next numbers have been multiplied by prime numbers... first;y by 2, then 3, then 7, then 43
and the answer of Cap, by 1807 and the other possibility, 1811 (which by the way is the next prime number)
3 is the 2rd prime number;
7 is the 3rd prime number including the 3rd prime;
but 43 isn't the 7th prime number after 7 inclusive... but the 11th..
That is quite confusing. Am I on the right track?

I'm not sure of Capuchin's other possibility.

Jerry, you're close to my logic, which was a(n) = a(n-1)*(next prime higher than a(n-1))
And Perito hit the logic behind my first answer,
